Landing chair controllable in direction

Abstract

The invention relates to a landing chair controllable in direction and relates to the field of aviation safety. The landing chair comprises an ejection chair, telescopic shafts, electric lift devices,a controller, a battery and an umbrella throwing device. The umbrella throwing device comprises a detection device, an ejection device and a parachute. The four telescopic shafts are symmetrically arranged below the ejection chair in the same height. The electric lift device is arranged at the tail end of each telescopic shaft. The controller is arranged inside the ejection chair, and the electric lift devices and the telescopic shafts are both electrically connected with the controller. The battery is arranged inside the ejection chair and supplies energy for the controller, the electric lift devices and the telescopic shafts. The detection device is arranged on the ejection chair and is connected with the controller. The ejection device comprises an ejection cylinder, a locking piece and an elastic piece, wherein the locking piece is arranged at the upper end of the ejection cylinder, and the elastic piece is arranged in the ejection cylinder. The parachute is arranged between the elastic piece and the locking piece, and the parachute is connected with the ejection chair at multiple points through a plurality of ropes. The landing chair can reduce the influence of the wind direction, and a pilot can manually control the landing chair to rapidly land on the designated ground after an air accident occurs.

Description

technical field [0001] The invention relates to the field of aviation safety, in particular to a direction-controllable landing chair. Background technique [0002] At present, most of the escape equipment used by aircraft when an air crash occurs is a parachute. On special aircraft such as some fighter jets and transport aircraft, ejection chairs are generally equipped so that the pilot can escape in time when an accident occurs. Traditional ejection chairs are often equipped with a parachute, but the parachute is greatly affected by the wind direction. After the pilot parachuted, he floated with the wind. The uncertainty of the landing location led to the ground rescue forces often needing to spend considerable effort to find the pilot. The parachute used in the first stage takes a long time in the landing process, and the air resistance suffered cannot be controlled. The above two major problems have led to the increase of rescue search difficulty and the long rescue tim...

AI Technical Summary

Problems solved by technology

Traditional ejection chairs are often equipped with a parachute, but the parachute is greatly affected by the wind direction. After the pilot parachuted, he floated with the wind. The uncertainty of the landing location led to the ground rescue forces often needing to spend considerable effort to find the pilot. The parachute used in the stage takes a long time to fall, and the air resistance it suffers cannot be controlled

The above two major problems have led to the increase of rescue search difficulty and the long rescue time

In the case of the wounded, if the rescue time is too long, the wounded will not be able to support their injuries and will not receive timely treatment, which will increase the chance of casualties
